SIPHON APPARATUS.

Application led October 15, 1921.

To all whom t may concern.'

Be it known that I, RODERICK l/Vnrn, a citizen of the United States, residing at Mobridge, in the county of l/Valworth and State of South Dakota, have invented certain new and useful Improvements in Siphon Apparatus, of which the following is a speciication, reference being had to the accompanying drawfings.

rlhis invention relates to water distribution devices, particularly to Siphon apparatus, and has for its object the provision of a Siphon apparatus adapted for use in connection with wells, ponds, lakes or other bodies of water whereby to supply water to a reservoir such as awater-hole for waten ing stock or for /any other purpose.

An important object is the provision of a Siphon apparatus having a pump associated therewith for starting the Siphon action, use being made moreover of a specially constructed check valve at the inlet end of the Siphon pipe.

r-i further and more Specific object is the provision of a Siphon apparatus in which the discharge pipe of the pump is connected with the Siphon pipe which has its inlet end carrying' `a gravity check valve provided with a constantly open relatively small hole, the arrangement being such that when the pump is initially operated water passing therethrough will discharge all the air from the Siphon pipe so as to facilitate starting the Siphon action.

An additional obj ect is the provision of an apparatus of this character which will be l simple and inexpensive in construction and installation, highly eliicient in use, positive in action, durable in service and a general improvement in the art.`

TWith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure 1 is a sectional view through a well illustrating my siphon apparatus in position; and

Figure 2 is a detail sectional view through the check valve.

Referring more particularly to the drawings, the letter A designates a well, at the top of which is mounted the usual platform Serial No. 507,872.

B upon which is secured a pump C of ordi nary type which has an inlet pipe D ci;- tending down into the well in the usual mar.- ner and carrying the ordinary cylinder l. instead of the usual spout the pump is provided with an outlet pipe 10 which connects with a T 11, having one branch closed by a plug 11EL and having connected with its other branch a pipe 12 which leads down into the well and which has its lower end carrying a check valve 13 of peculiar construction as will be hereinafter explained. interposed in the pipe 12 is a suitable cut off valve 1e and a union 1d@ of conventional pattern and connected with the pipe 12 at or near the platform B is a discharge pipe 15.

The check valve 13 comprises a casing` 16 having an inlet end 17 within which is located a straining screen 18 held in place by a ring 19 screwed on to the casing. This casing is provided at its opposite end wi th an internally threaded liange 2() into which is screwed the pipe l2. The casing may also be formed with a flanged extension 21 normally closed by a plug 22. fllxtending transversely of the casing 16 is a partition 2.9i formed with a central opening 241 which is normally closed by a liap valve 25 pivotcd within the casing. The partition 23 is formed with a relatively small hole 26 which is always open,

Assuming that my device has been rou structed and assembled above described, the operation is as follows: lVhen it is desired to start the siphoning action it is necessary to operate the pump C in the usual manner, the valve 1li of course being open. `Water passing from the pump will be forced through the pipe 12, some of the water passing into the pipe 15. As the water iS forced down the pipe 12 it will force out all the air from the pipe 12 through the hole 2G in the check valve casing so that in a ver).Y short time the pipe 12 will contain nothing' but water. Owing to the fact that the water cannot escape through the hole 26 with. as great rapidity as it is pumped into tln` pipe 12, it will be apparent that the water will be forced through the pipe 15, the discharge end of which is below the level of the check valve 13 whereupon the siphoning action will start as soon as the valve le is closed and the pumping action discontinued. It is then apparent that the water will continue to flow through the pipe 15, being drawn through the screen 18 and through the opening 24; in the check valve, the ila-p valve 25 of course being unseat-ed.

.ln order to provide against freezingot' the iva-ter within the pump andpipes in case the apparatus is not in operation, I provide the pump C with a small pet cocl27 and the pipe D with a Waste hole 28. lt will be obvious that When the'pet cock is` openthe Water within the pipe D and pump will drain back into the Well when `the pumpis standingl idle. rllhe cut off valve le `is pro vided with a hole 29 which permits draining out oit the Water above the valve.

The purposeot employing the .T l-l and plug- 1l in place of an L is that the plug .may be removed and the Well pumped .dry in case it is necessary to clean it, or repair the curbA ing or renew the screen A18,..al1 these being capable of accomplishment without interfein ing with the action of the siphon.

'lhe purpose ot' the hole 26 is three-fold: first,` to e'l'iect priming` of the siphon; second, t0 dra-in Water out of the pipe l2 when the siphon is stopped; and third, for cleaning the screen 18 Whenever the Siphon .isstarted .fis tar as the priming' action is concer-ned, the hole 26 would cause the same resultielgardless of its eXac-t location in the check valve7 though by forming the hole inthe partition7 the discharge` ot' Waterftlu'ougli the hole will wash away any debris or rubbish which may have accumulated. on the screen 15S during` the previous siphoning.

From the foregoing description and a study of the drawings it Will be .apparent that .l have thus provided an extremelysimple apparatus by means ot which WaterL may Vmeans of. an ordinary pump. The operation `maybe attendedto .even by aI child as no great intelligence and very little strength arenecessaiy @Wing to the simplicity of the construction it is apparent that there is nothing toget, out .of order and that the device should consequently have an extremely long life and eliciently perform all the functions: 'for which. it is intended.

.While l have shown and `described the preferred .embodiinentoi'V the invention it is ofcourseto beireadily understood that l reserve the right .to make suc-h changes in the form, construction and .arrangement ot parts aswillfnot .departfrom the spirit ot the invention or the scope of the sub-joined claim.

:Having thus described my invention, I claim:

The combination. with a Siphon-.embodying the usual inductionleg7 said leg being pro vided upon the `lower end thereof with a. screen, of means for 'orcing'fluid into said leg in a direction opposite to the normal, direction oi. flowtherethrough, anda check valve .disposed at the lower end. of said leg opening .in the direction. of normal flow and havingl `an openingpermitting passage of fluid atalltimes, said openingbeing smaller than the inlet for the oppositely directed fluid.
